PTSD as a Potential Post-Psychedelic Complication? Results from an International Online Survey.

Psychedelics show promise in treating mental disorders, but it is also known that a small proportion of users develop lasting psychological problems following their use. This talk presents data from an international online survey, showing that for some of these individuals, the symptoms can reach the severity of post-traumatic stress disorder (PTSD) as measured by the DSM-5. Symptoms often persist for several years and are strongly correlated with the intensity of challenging acute experiences. The findings suggest that, while potentially rare, psychedelic use can lead to severe psychological complications that may benefit from trauma-specific therapeutic interventions.
